Outlining is a method used to organize ideas and information before writing. It involves creating a structured framework that highlights the main points and supporting details of a topic. This process helps writers clarify their thoughts and ensures a logical flow in their work. There are different types of outlines, such as alphanumeric and decimal formats, which can be tailored to fit various writing projects. By using an outline, writers can easily identify gaps in their arguments and make adjustments, ultimately leading to a more coherent and effective final piece.
